How to identify the gemstones

Nature has created many varieties of jewelry stones with a full palette of colors and shades. That even an experienced specialist will not immediately distinguish them from natural ones. Modern scientific achievements make it possible to grow artificial stones of such quality.

More than 200 natural materials (gemstones and diamonds) are currently used to produce the jewelry. The jewelry industry also makes extensive use of synthetic and refined materials. There are a lot of products made of such materials on the market, and no one is immune from mistakes. Therefore, a modern woman needs to understand the variety of jewelry materials. It is essential to determine the quality and color characteristics of expensive stones: diamonds, sapphires, natural pearls.

The higher the cost of the stone and the demand for it, the more often unscrupulous people resort to various techniques aimed at "improving" the stone or imitating it. There is no term as "fake stone" in trading jewelry stones. There are imitation stones that are fakes of natural or synthetic stones. These stones mimic the effect, color, and appearance of natural stone. Still, they have a different chemical composition and other physical properties. A specialist can easily distinguish a fake with the help of devices.

 

What is an artificial stone?

 

Currently, jewelry with synthetic stones is widely represented on the market. The volume of their production is constantly growing, and synthesis technologies are being improved simultaneously.

Among the artificial stones presented on the market today, two groups stand out:

  1. Complete analogs of natural stones. A synthetic analog of a jeweler's stone is a mineral or rock. In their chemical composition, physical and optical properties fully correspond to a natural stone (artificially grown emerald, corundum - ruby, sapphire).
  2. Artificial stones obtained in the laboratory have no natural analogs (cubic zirconia, glass, etc.). Such stones serve as imitations of jewelry stones.

Jewelry stones obtained in laboratory or factory conditions, such as rubies, sapphires, emeralds, are almost indistinguishable from natural formations of similar composition in their appearance and physical properties. Both have identical colors, the same hardness and density, identical chemical composition, and optical properties. The slight differences between synthetic and natural stones are due to the specific conditions of their formation (crystallization). In nature, crystals grow slowly under pressure from hot aqueous solutions or molten magma. In natural stones, many chemical compounds are also required, which interact to form several different minerals under certain conditions. Therefore, when examining a natural stone, you can observe slight inclusions of other minerals formed with it or traces of the surrounding liquid in which it was created. Synthetic stones are grown in chemically cleaner conditions. Often the characteristic features of synthetic stones are their flawless transparency.

An accurate conclusion about the nature of the stone can only be obtained from a specialist after a thorough microscopic examination of your jewelry.
